Any player wanting to unlock Allied Races will need to level one character to level 40 and then complete the allied race unlock scenario. The allied race unlock scenario starts at the faction city embassy in either Stormwind or Orgrimmar.
This change came to World of Warcraft in Dragonflight Patch 10.1.5.
